Two big-money donors who have given or raised tens of thousands of dollars for Donald Trump are livid at the Republican presidential nominee and are asking for their money back, according to a bundler who raised money for Trump.

“I cannot express my disappointment enough regarding the recent events surrounding Mr. Trump,” one donor wrote to a Trump fundraiser in an email with the subject line “Trump support withdrawal.”

“I regret coming to the Trump support event, and in particular allowing my son to be a part of it,” the donor, who had given to and raised money for Trump, said. “I respectfully request that my money be refunded.”

Senior Trump spokesman Jason Miller said the campaign is “unaware of any donors making such a request.”
